Enum Model 

pub enum Model {
    Claude3Haiku20240307,
    Claude3Sonnet20240229,
    Claude3Opus20240229,
    Claude35Sonnet20241022,

}

Available Claude models with their capabilities and token limits.

Each model has different strengths, speeds, and costs. Choose the model that best fits your use case:

• Haiku: Fastest and most cost-effective for simple tasks
• Sonnet: Balanced performance for most applications
• Opus: Most capable for complex reasoning tasks

Examples

use anthropic_rust::Model;

// Get the maximum tokens for a model
let max_tokens = Model::Claude35Sonnet20241022.max_tokens();
println!("Max tokens: {}", max_tokens);

// Compare models
assert_eq!(Model::Claude3Haiku20240307.max_tokens(), 200_000);

Implementations

impl Model

pub fn max_tokens(&self) -> u32

Returns the maximum tokens supported by this model

Trait Implementations

impl Clone for Model

fn clone(&self) -> Model

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Model

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Model

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Model

fn eq(&self, other: &Model) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Model

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Model

impl StructuralPartialEq for Model
